Seperate lines for people w/ disabilities

My condition is not visible. I look perfectly healthy on the outside, but I am severely disabled. My entire autonomic nervous system does not function when I stand upright. (Breathing, heart rate, digestion, blood pressure, body temp, sweat, blood circulation, etc) I cannot stand in lines, and cannot walk for long periods of time. It would help if businesses had queues for people with disabilities who cannot stand up for long periods of time, or wait in lines. Covid has made it impossible for me to shop in any grocery store, or any retail store whatsoever. I would faint waiting in the line with my condition and end up in hospital. (It’s called Postural Orthostatic Tachycardia Syndrome)
